Hibernate will generate the database schema definition and create the 
tables if we ask it do; we have done this a couple of times at SDSC.  Or 
did I misunderstand this point?

Right now the TB1 data is nearly all installed in the new TB2 database 
at SDSC.  Since the SDSC and NESCent scemas will be identical, or nearly 
so, the data migration from SDSC to NESCent should be straightforward. 
I understand there is probably some way to dump the TB2-format data as 
it currently exists at SDSC, transfer the dump files to NESCent, and 
bulk-load them into the database on the NESCent side.

I would not like to perform the TB1->TB2 migration a second time, if at 
all possible.

The current codebase is severely lacking in unit tests.  What tests 
there are are often extremely slow and are more properly system tests 
than unit tests.
